Some pictures from my recently acquired Triumph Adler typewriter (cherry MY switch, pbt keycaps). Cherry MX clicky switch.

I would have thought typewriters were replaced with PCs after Cherry MX came out. How do these compare with Selectric?

Remember that for a long time PCs were far more expensive, not to mention slower (...) and more difficult to use. Home computers were fiddly and very limited. Also, output from a 9-pin dot matrix printer did not give a very good impression compared to a type-written page.
It was also very much a question of habit. My dad used typewriters for writing pretty much everything, including addresses on envelopes, VHS cassette labels, filling out forms, etc.

Selectric had keys on key-arms, like earlier typewriters. The keys were tactile.
Linear switches seems to be as being the norm for electronic typewriters.

Not quite right, I have also a TA typewriter with MX switches. The switches are cherry MY, but because they are old style, they feel quite nice (compared to the new style).

There are also clicky typewriters, like the one with IBM buckling springs.
